Actually it mostly does. Or rather, it uses an updated and futzed with version of the Skyrim engine (that is, I believe, and updated and futzed with version of the previous engines.) People are using Skyrim mod tools to make at least basic mods until the new GECK is released, they are that similar. For cheats, '~' still brings up Ye Olde Console, player.additem, player.modav, etc still do what you expect, etc.
